Interpower Strain Reliefs/Cable Glands

A strain relief or cable gland secures the cable of a power cord to the panel of the electrical equipment. It provides protection to the wires and cables from stress and damage as it runs through the panel of the equipment. It does not relieve strain on a cable as it exits the equipment, but it relieves the strain on the electrical connection and circuitry inside the equipment. The term “strain relief” is commonly used in North America, while “cable gland” is commonly used throughout Europe and the other parts of the world.

Strain Reliefs/Cable Glands Available at Interpower

There are many different sizes for each type of strain relief/cable gland. To see what is available, see Strain Reliefs/Cable Glands on the Interpower website or click on the link for specific dimensions.

Using a Conduit

Interpower also offers conduit for use with nipples or elbows. This highly flexible corrugated conduit is made of Nylon 6/6 and is flame-retardant and self-extinguishing. It features excellent crush resistance, resistance to heat, UV exposure, and certain chemicals. Wires or cable are threaded through conduit in situations where the wire and cable need extra protection (from elements or physical damage) or where users may need to add additional wires at a later time.
